I have an Application, my first Application
with DOA & Delphi 5.0, and when I try to open
the TwwOracleDataSet is very slow (10 seconds) to open the Table. Whe i Begin to design the Application are very fast because
there is few records.

Someone knows what happend?

In ADO there is one property to fetch a few records and the rest fetchs on background.

The TOracleDataSet has a QueryAllRecords property. When you set it to False, only the visible records will initially be queried. The default value of this property is True, because we assume that you are always interested in the complete result set. If this is not the case, you should probably modify the where clause of your query.
